specifying a symlink for the preseed does not work

[Paul Larson]

In this job log: http://10.98.0.1:8080/view/Raring/view/Smoke%20Testing/job/raring-server-i386-smoke-floodlight/27/console

We see that the job specifies a bzr path to the location of the preseed. The file in bzr at that location is a symlink, and utah doesn't seem to be able to dereference it.

Here's the failing section and errors:

Our bzr url support currently fails on symlinks. I'll work on a fix.

[Max Brustkern (nuclearbob)]

I've tested a fix that we can work on getting into a new package. As a further note, floodlight.preseed is currently symlinked to default.preseed. If floodlight.pressed does not exist, but default.preseed does, we'll use default.preseed, so in the future, you can just leave out preseeds that are the same as the default one.
